Not execute before save action in extension(XBO) PDI

1. At the moment that I release an Outbound Delivery document you can see the system raises a standard error, for example in this case because the logistic area doesn’t have enough stock (but can be another kind of error).
2. In my customer solution I have ABSL code in the before save action. However, this is being executed even if the system raises a standard error.

My need is that the ABSL code shouldn’t be executed at the moment the system raises an error. Only when the document - by standard - will be save because doesn’t have any error.
